Abstract: 1,005,962. Screw and nut gearing. ROTAX Ltd. April 1, 1963 [April 5, 1962], No. 13205/62. Heading F2Q. Associated with a ball typo screw and nut mechanism is a member 13, having limited angular freedom relative to the nut 4 and a helical rib engaging the groove 3 in the screw 1, so arranged that during relative rotation of the screw and nut in one direction the rib moves freely in the groove 3, but during rotation in the opposite direction the rib binds in the groove, thus resisting rotation, e.g. to prevent a load on a lifting apparatus from causing the screw to rotate. The nut 4, housing members 5, 10, and a spacer ring 7, are fast with a body 2 of a lifting apparatus and the member 13 has end clearance 17 in the housing 10. When the shaft is rotated so as to move to the right the member 13 will be driven against a thrust bearing 14 so that it binds on the screw 1 and prevents further rotation of the latter. A release device (Fig. 2, not shown) enables the member 13 to be turned slightly to take up the clearance 17 and allow free rotation of the screw 1 in the previously resisted direction.

Title: Improvements in or relating to sound recording apparatus for cinematograph films
IPC: G03B31/00
Filed: 1950-05-25
Abstract: 679,282. Combined sound and picture apparatus. LEEVERS, F. N. G. May 10, 1951. [May 25, 1950] No' 13233/50. Drawings to Specification. Class 40 (ii). [Also in Group XXXV] A method or apparatus for producing a sound record in synchronisation with a kinematograph picture film, comprises recording the sound on one part of the width of a magnetic record tape and simultaneously recording alongside the sound track a pulse signal generated in synchronism with the frames on the picture film. The sound record may then be reproduced, or recorded on a combined sound and picture film, in synchronism with the pictures by adjusting the speed of the magnetic tape so that the pulses thereon are synchronous with pulses produced by the picture film mechanism. The speed of the sound film may be automatically controlled, when reproducing or recording on the combined sound and picture film by providing a driving means which tends to move the sound film too fast, but is slowed down by a brake controlled by a difference signal produced from the recorded pulse and the pulse from the picture film mechanism. The recorded pulse may be in the form of a pulse-modulated carrier wave produced by an oscillator having a carrier frequency of 1,000 to 5,000 cycles/second and modulated by a. generator driven by the picture mechanism.

Abstract: 889,174. Q-factor measuring. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 11, 1960 [April 22, 1959], No. 13728/59. Class 37. In apparatus for measuring the Q-factor of a cavity, a modulated carrier-wave having a frequency equal to the resonant frequency of the cavity is fed to the cavity, and the output of the cavity is compared in magnitude with a wave derived from the modulated carrier-wave. In one embodiment, a generator A supplies a reflecting cavity 2 with the modulated carrier over a waveguide 1, the output of the cavity being coupled into a waveguide 4 through a 3 db coupler 6. The output of generator A is coupled into waveguide 3 through a loose 20 db coupler 5 and is passed through a variable phase-shifter 10 and a variable attenuator 11 to obtain a wave of known magnitude which is out of phase with at least one sideband of the cavity output. The wave so obtained is coupled into waveguide 4 and is compared with the cavity output in spectrometer 8, phaseshifter 10 and attenuator 11 being adjusted to null first one sideband and then the other to determine the degree of attenuation of the sidebands caused by cavity 2 and hence the Q- factor. Preferably both sidebands are simultaneously compared in two separate spectrometers 8, 13 (or a double-beam spectrometer), coupler 9 then being a 3 db coupler and the upper and lower sideband being annulled in spectrometer 13, 8 respectively. A similar arrangement, Fig. 2 (not shown), may be used for measuring the Q-factor of a transmitting cavity.
